Abstract
Abstract A plastic article is rotated about an axis of rotation and a cutting blade mounted on a pivotal arm is moved towards the rotating article proximate a groove therein where the article is to be cut. The arm is resiliently supported to permit transverse movement therein parallel to the axis of rotation and when the blade is lowered against the article, it rides along an inclined surface adjacent the groove so as to be guided into the groove to effect the removable of the undesired waste on the article beyond the groove.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
152 words
Apparatus for cutting articles of plastic material comprising means for rotating an article to be cut about a fixed axis of rotation, a cutting blade, an axle extending parallel to said axis of rotation of the article, a cover mounted on said axle for pivotal movement about the axis thereof, an arm carried by said cover and supporting said cutting blade for movement in a plane perpendicular to said axis of rotation of the article towards and away from the article proximate a groove therein whereat the article is to be cut, and means pivotably mounting said arm on said cover for transverse movement in opposite directions parallel to said axis of rotation of the article, the article having an inclined surface adjacent said groove and facing said cutting blade to guide the cutting blade into said groove by transverse movement of the blade when the blade is moved towards the article.
Claim 2
Dependent Claim
152 words
Apparatus for cutting articles of plastic material comprising means for rotating an article to be cut about a fixed axis of rotation, a cutting blade, an axle extending parallel to said axis of rotation of the article, a cover mounted on said axle for pivotal movement about the axis thereof, an arm carried by said cover and supporting said cutting blade for movement in a plane perpendicular to said axis of rotation of the article towards and away from the article proximate a groove therein whereat the article is to be cut, and means pivotably mounting said arm on said cover for transverse movement in opposite directions parallel to said axis of rotation of the article, the article having an inclined surface adjacent said groove and facing said cutting blade to guide the cutting blade into said groove by transverse movement of the blade when the blade is moved towards the article.
Claim 3
Dependent Claim
48 words
Apparatus as claimed in claim 1 comprising abutment means for said cutting blade to limit transverse movement thereof in the direction opposite that in which the blade moves when it enters said groove, and spring means acting on said arm to urge the same against said abutment means.
